Summary of Changes

Added UAMI Support

• Added UAMI support for Data Sync cmdlets.
• Introduced three new parameters across New-* and Update-* cmdlets:
  • HubDatabaseAuthenticationType
  • MemberDatabaseAuthenticationType
  • IdentityId

These parameters allow customers to:

• Select authentication type (Password or UserAssigned)
• Optionally provide a user-assigned identity.

---

Backward Compatibility

- No visible changes in behavior
- Password-based authentication continues to work without requiring new parameters.

---

Validation Logic

• Password authentication
  • Requires Username and Password.
• UserAssigned authentication
  • Requires IdentityId when creating new resources.
• Update behavior
  • If UserAssigned is specified without IdentityId, cmdlet preserves the existing identity instead of throwing.
  • This supports partial updates intentionally.

---

Help and Documentation

• Updated cmdlet help files with:
  • New parameters and their accepted values (Password, UserAssigned)
  • Examples for both password and UAMI flows.

---

Resource Strings

• Added localized error messages for:
  • Missing credentials
  • Missing IdentityId
  • Invalid authentication type

---

Testing

• scenario tests for control Plane operations
  • Data Sync scenario tests record once and capture API responses.
  • Since the new API version is not yet available in stage, reliable baselines cannot be recorded.
• Extensive Testing Done in Staging with changes
  • Complete info of testing done with testcases can be found here:

This is a copy of old PR which was reviewed and approved

[hareeshghk]

Overall looks good, added two comments

[hareeshghk]

here its written as resource id and also in tests but PT description says IdentityId, can you update one.
Also have you tested with latest changes of DsMainDev as few changes and new validations went into DsMainDev after your previous powershell testing

[hareeshghk]

This about user experience, is it better to add an extra parameter like this or we only get the syncgroup and member first to receive resourceid and add a confirmation saying that "adding new UAMI will remove existing one" , just as a suggetsions, this also looks good
